NSEC Safety Briefing: 

NSEC Safety Briefing Lab Etiquette Fume Hoods Personal Protection Equipment Hazardous Waste Emergency Procedures Chemical Spills Medical and other emergencies

Slide3: 

Proper Work Practices in the Laboratory Proper Handling of Chemicals and Equipment Conduct, Behavior Attire Head bouffant cap, blue gown, booties

Slide4: 

Do not store chemicals or equipment on the floor Clean up for the next person Always be courteous and careful Maintain adequate isle space Know location of: - Protective Equipment - Fire extinguisher - Safety Shower - Eye Wash - Spill Response Kit - First Aid Kit Proper Work Practices in the Laboratory

Slide5: 

Chemical Fume Hoods Before starting an experiment, know all the physical, chemical, and toxicological properties of all the materials with which you will be working with.

Slide6: 

Fume Hood Guidelines Work at least 4 - 6” inside hood. Lower the sash to the lowest practicable position.

Slide7: 

Fume Hood Guidelines Keep hood surfaces clear and baffles unobstructed to allow proper airflow. Airflow in a fume hood is easily disrupted; do not use the fume hood for storage!

Slide8: 

Personal Protective Equipment

Slide9: 

Eye Protection When working with chemicals, when working near someone working with chemicals, when working around chemicals, but not directly with chemicals themselves, Please! – always wear some form of eye protection!

Slide10: 

Types of Eye Protection Regular safety glasses provide sub-maximum protection, and can allow splashes and chemical vapors to reach eyes. Prescription safety glasses have corrective lenses, but provide only the same degree of protection as regular safety glasses.

Slide11: 

Types of Eye Protection Goggles provide the most protection, forming a seal against the face. Laser goggles have wavelength-specific lenses and opaque non-lens components.

Slide12: 

Hand Protection Glove materials (PVA nitrile, butyl, PVC) show different degrees of resistance to chemicals Heavier gloves = greater chemical resistance, but less dexterity Thin exam gloves (esp. latex) provide almost NO chemical resistance See MSDS for proper glove selection

Slide13: 

Labcoats Labcoats provide extremely limited but critical protection from chemical splashes Useful when working with small (i.e., research sized) quantities of hazardous chemicals Heavily contaminated, well-worn labcoats must either disposed of or laundered, before they become sources of exposure themselves

Slide14: 

Corrosive Liquids Most common cause of corrosive injury Corrosive liquids will destroy any living tissue but the most frequently injured organs are the skin and eyes. Corrosive vapors can also escape from some solutions (check out the interior of any acid cabinet). Fuming acids are particularly hazardous

Slide15: 

Corrosive Liquids: Bases Concentrated alkalies are more damaging to tissues than most strong inorganic acids Alkaline solutions gelatinize and saponify tissues, producing deeply penetrating, painful burns Even weak alkaline solutions can dissolve skin fats and weaken the epidermis, making the skin more permeable to other agents Initial contact may not be painful – poor warning property!

Slide16: 

Corrosive Liquids: Acids Chemical action of acids is different from that of bases. Acids burn largely due to thermal action with moisture in tissues. When acids come into contact with skin, the acid reacts to form a (very slightly) protective barrier, whereas bases dissolve proteins.

Slide17: 

Corrosive Liquids: Hydrofluoric acid/Piranha HF is extremely dangerous not only because it is an acid but because the fluoride ion is capable of traveling through layers of tissue on its way to the bone, producing severe, slow healing burns Always store/use HF solutions and hydrogen HF and gaseous hydrogen fluoride merit special discussion. These are easily the most hazardous corrosive materials encountered in the laboratory Fluoride gas in a chemical fume hood – never on the lab bench! No HF or Piranha after 6PM, Make sure that all YR users are aware of what you are doing!

Slide18: 

Emergency Procedures Spills/releases of hazardous materials Medical Emergencies Power Failure Fire

Slide19: 

What should lab user do in the event of a spill? If the spill occurs outside of a fume hood (i.e., chemical vapors/fumes are uncontained), all lab personnel must leave the room. Call EH&RS at x4-8749, or Security at x99 (after regular working hours only. Give the exact name of the chemical spilled, the amount, and the exact location of the spill (building/room/location within room).

Slide20: 

What should lab user do in the event of a spill? If a chemical has splashed on you, or on another lab member, immediately wash it off with copious amounts of water, for at least 15 minutes. Call for medical attention only after washing.

Slide21: 

Chemical splash in the eyes! Flood eyes with copious amounts of water at eyewash for at least 15 minutes, then seek medical attention.

Slide22: 

Spills/Releases of Hazardous Materials Do not attempt to clean up a hazardous spill yourself; you could be exposing yourself to great danger! Notify Lab personnel immediately if a spill occurs; evacuate area EH&RS personnel clean up all spills of hazardous materials. Chemical spill absorbent pads are kept in the cabinet above the spill kit Spill kits are to be used by Lab personnel only

Slide23: 

Reporting a Fire Incidents not related to Columbia University Dial 911 Campus Rolm phone system Dial 99 Manual Pull Stations Located at Exits

Slide24: 

When to Sound a Fire Alarm ANY Fire or Smoke Condition Dangerous Situation Crime in Progress, Suspicious activities For Emergency Building Evacuation

Slide25: 

Laboratory Evacuation Procedures Turn Off All Apparatus Within Reach That Can Be Safely Turned Off Close All Chemical Containers That You Are Working With (especially volatiles; such as acetone and alcohols) Close Fume Hood Sash

Slide26: 

Laboratory Evacuation Procedures Know Location Of Fire Exit, Count Number of Doors Look For Exit Sign (Always illuminated/Emergency Lights) Use Nearest Stair Do Not Use Elevator Exit Building And Move Away From Door To Allow Security And Fire Department Access

Slide27: 

Medical Emergencies For minor injuries: go to Health Services on the 3rd floor of John Jay Hall (114th st. & Amsterdam Ave., southeast corner of campus). For more serious medical emergencies (unconsciousness, chest pain, breathing stops, deep cuts requiring stitches, etc.) call Security at x99. Do NOT call 911!

Slide28: 

Medical Emergencies Incidents not related to Columbia University Dial 911 Campus Rolm phone system Dial 99 Columbia Area Volunteer Ambulance http://www.columbia.edu/cu/cava/home.html

Slide29: 

Other Emergencies Fume hood failure: call x4-4899 (Area D) or call EH&RS, x4-8749. General power failure: close fume hoods, keep refrigerators/cold rooms closed, stop working! If fire alarm is heard exit cleanroom immediately into hallway, use emergency stairs to 4th floor and exit building.

Slide30: 

Hazardous Waste Management How Do You Handle Hazardous Waste?

Slide31: 

Hazardous Waste Management How do You Handle Hazardous Waste? The four primary objectives in waste management are: 1- Produce as little waste as possible 2- Reduce the toxicity of the waste by segregating into different streams 3- Minimize the potential for release to the environment 4- Reduce your risk of exposure

Slide32: 

Hazardous Waste Management How do You Handle Hazardous Waste? Make use of all available PPE Dispose of all garments and PPE that have come into contact with hazardous waste materials Never be in a rush to complete an experiment; especially where hazardous chemicals are involved

Slide33: 

Hazardous Waste Management How do You Handle Hazardous Waste? Users are responsible for their own waste All chemicals are disposed of in labeled waste containers (Stored in Hazardous Waste Area) No chemicals are to be disposed of down the drain Do not carry open containers around in Yellow Room Fill waste containers under chemical fume hoods Rinse all glassware and plastic ware when finished

Slide34:
